I My invention relates to thatltype of fleX i ble outside metal car roof, wherein the roof- `ing'she'ets extendfroin eaves to ridge of the y car and are arranged for sluing or oscillatory i movement thereonv n accommodating them:

selves to the-distortion of the car-body.

Vtion is an improvedseainconstruction that Will secure lan independent oscillatory or sluf in points located in the region. of4 the middle oftheir adjacent margins'whenever there is' imovement of said sheets."

*Y Bythe arrangement described, the pivot -pieces and the ridge 'seam covers have linev 45 f y contact with the outer Vand inner sides olf the ridge flanges of the sheets midway ot: their ridge ends and arev spaced therefrom 'at their ridge corners, whereby the sheets Vare Vpermitted to accommodate 'themselves to dis`- tortion of the car frame by pivotingl orfsjlii ing about Vthe'contact-ing portions ofvsaid pivot members and said ridge seam cover. Itis noted as an important advantage of my inventionthat it utilizes the saddle bolts ris a means for .securing` the pivot pieces ini place and thereby saves the'cost'of separate vfastening members for said pivot pieces and facilitates assembly of the latter on the cai; bviously, the hereinbefore described ar' rangement admits of considerable modiiicaftion Without departing from the invention; therefore I .do not Wish to be limited to the recise arrangement shown and described. or instance, the pivot pieces and the ridge seam` covers may be given the necessary taper by means oitV reversely curved surfaces. y i
